A color display system that is capable of taking input intended to be displayed on a full color display (e.g. VDU) having a high refresh rate and displaying the image on a display having a much reduced number of displayable colors and a lower refresh rate. 24-bit RGB data is input and converted into bi-level RGBW data and halftoned in a render unit for storage before display. Motion detection is used to ensure that only those pixels that have change in value are updated on the display.

Color display system

Display standards in common use for the display of computer or television images on high resolution displays, commonly assume that the output image will be displayed on a output device having a high refresh rate. A high refresh rate is normally required to avoid the viewer observing flicker, stilted motion or other visual artifacts if a lower refresh rate were used. It is difficult to drive a high resolution Ferroelectric Liquid Crystal Display at a high refresh rate. The subject apparatus is provided for using the memory function characteristics of such a display and driving such a display at a slower refresh rate while still maintaining the appearance of a device having a higher refresh rate by refreshing those portions of the screen where motion has been detected at a high rate and only occasionally refreshing the whole screen.
